A novel solar-fuel assisted thermophotovoltaic system and parametrical analysis

In this study, a thermal-balance model is established for energy calculation of new solar-fuel assisted thermophotovoltaic system, which could save fossil fuels and improve the grade solar energy. The coupling effects key parameters such as concentrate ratio, absorber area, emitter etc. on system efficiency are determined. Besides, effect fuel saving investigated. results show that can not only increase output power photovoltaic cells by nearly 25 kW/m2compared to fuel-driven but also electrical 10 percentage points. Furthermore, it saves up 76%. It pointed out improving absorptance optimization. This study provides reference design application technology.
